IPERFORATING-MACHIN ATTACHMET.

Application filed Gc'cober 27, 1924. Serial No. 746,059.

To @ZZ 'whom t may concern.'

lic it known that I, CHARLES I). HIGHLAND,

a 4citizen of the United States, anda resident of Des Weines, in the county of Polk and State of Iowa., have invented a certain new and useful Perforating-Wachine Attachment, of which the following is a specification.

My invention has to do with an attachment for use with a perforating machine of the suoli needles effective.

A further object is to providesuch an attachment which can be readily and easily adjusted for making effective any desired selection 4of the punches or needles. EWith these and other objects in view, my invention consists in the construction, ai rangement and combination of the various parts of my perforating machine attachment, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows an elevation of a portion of a perforating machine equipped with an attachment embodying my invention.A

Figure 2 is a horizontal, sectional view taken on the line 2-2of Figure 1.v

Figure 3 is a vertical, sectional view taken on the lined-3 of Figure =1.`

Figure 4- is a similar view line 1 4 of Figure 1L 7 Figure 5 is a detail, sectional view takenk on the line 5-5 of Figure 2.

Figure 6 yis a sectional view taken on the line 6 6 of Figure 1; and

Figure 7 is an end elevation of the frame forming a part of my attachment.

In the accompanying drawings, I have used the reference numeral 10 to indicate the leed or base of a perforating machine, whichha's at the'sidesthe upright posts 11. 'Ihe perforator 'head consistsof an upright member i12`havinwat its ends tubular guide elem-ents 13 mounted for vertical, sliding reciproeation on the posts 11. .Actuating taken on the bars 1.4i are pivoted to the tubular members or sleeves 13 and aresuitably operated from other mechanism, not shown, for reciproeating the perforator head.

At its lower portion, the head is provided on what I shall for convenience call its .front side with a Llongitudinal rabbet 1G against the rear wall of which is mounted the upright fiange 17 of an angle bar hav ing the lower horizontal iiange 18. For conv'enience, I shall call this angle bar the pin carrier bar. Y

In the flange 18 of the pin carrier bar or stripperare vertically and slidably mounted `a series of pins or punches 19, having at their upper ends heads 2O adapted to drop into the countersunk portions 21, so that when the pins'arefat their lower limit of movement, the tops `of their heads are'flush with the upper surface of the flange 18.`

At the sides ofthe bed 10 are plates or the like 22upon which rests a cross bar 23 shown for instance in Figures 3 and L located just rearwardly with relation tothe perforated head 12.

`Fastened as for instance byV small screws 24, illustrated in Figure 8, to the forward edge of the plate 23 is a pin` guide bar 25 arranged below the flange 18 and provided with a series of holes 26 arranged in registry with the respective pins` 19 and adapted to serve as a guide for the pins.

The sheets of paper 27 are shoved under the plate 23 and pin guide 25 when the head is raised enough so Vthat the lower ends of the pins 19 are retracted within the guide 25.

Thebed plate or `base 10 has holes 28 below the respective pins 19 and holes 2G to cooperate with the pins 19 duringvthe i,nincliing operation and to permit thepunch lo drop downwardly. i

Secured to the front face of the flange ll" substantially above the lower flange 18 of the pin carrier bar is a plate or bar 29, which is so located that if the head .12 is given its downward stroke, and apiece of paper is placed in position on the bed 10 above the holes 28, the pins 19will strike the piece of -m paper and will simply permit the head to slide downwardly without causing the' pins. to perforate the paper.

It is well known that for different kinds ofvoperations and different productions, it issometimes desirable to usevone group of pins 19 and sometimes touse another rgroup of p ins 19 in punching` a row of holes in a sheet of paper. My improved attachment is peculiarly adapted for enabling the user of the machine to select and determine whicl'. pins shall be operative and which :inoperative. p' 1 My device includes a plurality of members adapted to be inserted below the bar 29 above the pins selecte-d for operation, so that when the perforator head is lowered, the proper pins willbe. forced downwardly through the papers for perfora-ting the same.

My improved attachment includes the bar 29 already mentioned, which, however, is made detachable and is fastened in place by means of screws 'lOtsee Figure 3). At the ends of' the bar 29 are parallel lforward-ly extending end members 3l, having 'hori- 'zent-al slots 52, opening forwardly and projecting into the end members 3l for .a subs stantial distance and having counter-sunk portions 33 around their inner ends onA the outer sides of such end members.v

In connectionwith the bar 29 and the ends 31, as' thus described, I provide a rod 34 adapted to be slidinto the slots The rod 34 has the screw-threadedA ends 35 on which are nuts 36 or the. like having hubs 37 with beveled ends 38 adapted to coact with thecountersunk portions 33. Rigidly fixed on the rod 34 near one'end `thereof is a collar 39 adapted to abut'against 'the inner face of one of the end members 3l when the device is assembled. v Rotatably mounted on the' rod 34 is series of what I shallA call pin fin-gers 40. lIhese pin fingers 40 havefin gen-eral the shape of a bell crank lever with a projecting end 402L and 40. On the end 40" is a short projection 4l (see Figure 3) for engagement with the fingers of the operator.

The pin fingers 40 are so shaped and ar- 'anged that when the end portions 40a is upright, it rests against the bar 29 in the assembled position of the device, while when the fingers 40 aretilted over the ends 402L rest just below the bar 29, the two positions of the fingers being illustrated inFigures 4 and 3.

On the ends of the rod 34 aretighteuing nuts 42. i y Y htlyimproved attachment Jis used preferablyiu connection' with a gradiiated ruler 43,'shown in Figures 2`and 3.v The ruler 43 is inset into the' upper surface'v of a bar 44. vOne edge of the bar- 44 is beveled as at 45.

In the use of my attachment, the rloar 29 is placed above the ruler as shown for instance in Figures 2 and 3 with the ends 402L of the pin fingers 40 upright as illus'- trated in Figure 4 and 'resting upon the `surface of the bar 44.-

The bar 44 lhas notehe's't in'its ends The iper-es arey then-sismaietd the .position which they occupy in the machine when ready for use.

The upper part of the edge of the har 44, which has the beveled portion 45 abuts against the flange 18.

The ent-ire attachment is then pulled away from the head 12 slightly, the rod 34 is drawn part' way out in the slots 32, and the fingers 40, which are intended to be operative in connection with the pins 19 that-are to be actuated, aretilted over until they rest in theposition illustrated by the lingers 40 in Figure 3.

lVhen all of thedesired fingers 4() have been tilted, the rod`34 is shoved into the slots 82 to the closed ends thereof, and the righthand nut 42 is tightened for thus locking the fingers tightly betwen the collar 39 and the right-hand end member The left hand nut 42 is then tightened lo lock the rod 34 to the bar 30.'v

The entire attachment is then sho into proper position on the machine and the bar 29 is fastened in place by means ofv the screws 30, after vwhich the bar 44 is removed, leaving the parts yin the position illustrated in Fio'ure 4, except as to those fingers which vneve been tilted over to the position illustrated in Figure 3. y Y

I provide j a spring` clip 46 pivotally mounted onthe screw bolt 47so that lit can be swung out of the wayV and when in use can be swung down to press against one or two of the fingers 40 for preventing thel -forward spring of the rod 84. y

It will be understood that the graduated ruler 48 is employed to determine ust for what particular distances the fingers 40 are to be tilted to make them operative.

IVhen thev parts have thus been arranged and assembled and mounted on the machine, the machine is ready for use in perforatiugsheets of paper for the desired distances.

IVhen the head is reciprocated, it will be seen thaton its downward stroke, the pinsI or punches 19 will be actuated wherever the fingers` 40 havebeen tilted to the position shown in Figure 3.

lfVherever the fingers 40 are' inthe position shown in Figure 4', it will be obvious that on the downward stroke ofthe head,

the pins 19 will be engaged by the paper 2T and will slide upwardlywith their heads in the if'acant 'space below the bar 29. After the paper has beenperforate'd, the head 12 rises and the perforated sheets are removed and new sheets inserted for perforation.

TheA saving in time, which is accomplished with a device of this lrinchperhaps can be best explainedby referring to the method now commonly i-n use vfor accomplishing the functions performedA by niv-attachment.

'Where` xiiy attachment is not employed, th .common method is yto use small filler strips for blocks kabove tjlie flange 18 and lielow the bar 29. These blocks are olf various lengths.

Filler blocks ol' the proper lengths are inserre-d in the proper places for causing the desired pins l) to be actuated. This is a rather slow process and is particularly undesirable in that where careful work is ie quired, it is almost impossible to select filler blocks.l so as to perforate to exactly the right point on the sheet of paper. For instance` it will be noticed in examining a sheet of checks,' where two orthree checks are printed on a sheet and a perforation is made from top to bottom ol the sheet and other perfcrations between the separate checks, it frequently occurs that the horizontal. pert'orations do not extend quite to the line ot the vertical perforation-s. diliiculty in securing; exactly the right lengths of filler blocks.

lilith my device, quicker and more accuH rate work can be accomplished.

Furthermore. my lingers always remain exactly in position after they have been set, whereas `.Frequently the filler bloc is shift a little from the proper position causing inaccuracy7 in the work and sometimes causing` the spoilage of sonic sheets.

l claim as my invention z`- l. The combination of a perlforatingY machine having` a bed, a pin guide spaced above the bed, a pin actuating head adapted :tor reciprocation provided with a pin carrier bar or stripper, pins in said car 1ier bar, and guide, a bar on the head above the pins and spaced above them when they are in their lower position with an attachment comprising a rod, means for supporting said roden the reciprocating head, a plurality ot' pin lingers rotatably mounted on said rod and provided with extensions adapted in one position of rotation of the pin lingers to rest beneath said last described bar and above the pins and in another position to leave This is due to the the space between the said last-named bar and the pins open.

2. The combination ol a pertorating machine ha-ving a bed, a pin guide spaced above the bed, a pin actuating` head adapted for reciprocationprovided with a pin carrier bar or stripper, pins in said carrier bar and gui-de, a bar on the head above the pins and spaced above them when they are in their lower position, with an attachment comprising a rod, means lor supporting said rod on the reciprocating' head, a plurality of pin lingers rotatably mounted on said rod and provided with extensions adapted in one position of rotation oit the pin lingers to rest beneath said last described bar and above the pins and in another position to leave the space between the said last-named bar and the pins open, each `pin linger being of a thickness to enable it to coact with one pin only.

3. In an attachment `for pertorating machines, a. rod, a plurality of' pin lingers rotatably mounted thereon, each provided with an extension so arranged that when the linger is in one position of its rotation, the extension will be `spaced from a vertical plane through the rod and may be projected between the heads of the pin and the actuating bar of a perforating machine.

4. In an attachment for perforating` Ainachines, a rod7 a plurality of pin fingers rotatably mounted thereon, each provided with an extension so arranged that when the linger is in one position ci its rotation. the extension will be spaced from a vertical plane through the rod and may be projected between the heads of the pin and the actuating' bar of a perforatinf: machine, each p-in linger being ol' a thickness to cooperate with one pin.
